Grove.py install problem

I used "curl -sL https://github.com/Seeed-Studio/grove.py/raw/master/install.sh | sudo bash -s -" and then, result was - Grove.py installation FAILED, FAILED, FAILED . Can someone help?

According to the Internet, this only seems to run on Buster. https://forum.seeedstudio.com/t/grove-hat-grove-py-installation-failed-failed-failed/261665/3 https://github.com/Seeed-Studio/grove.py/issues/28 https://github.com/Seeed-Studio/grove.py/issues/46

Right, how can I install Buster? I read about this, but I can't find any tips
